Question

10. Find the continued product: (i) (x + 1)(x - 1)(x2 + 1)​

Answer 1

(x+1)(x-1)(x²+1)

=(x²-1)(x²+1) [a²-b²=(a+b)(a-b)]

=(x⁴-1) [a²-b²=(a+b)(a-b)]

Hence, the solution is (x⁴-1).

Hope it helps you...

Pls mrk me brainliest...

Answer 2

Step-by-step explanation:

x + 1 = 0

x = -1

x - 1 =0

x = 1

x² + 1 =0

x² = 1

x = +1 or -1

But I don't know the continued product.

it can be also known as( x+1)(x-1) = x²+1² = x²+1

Next may be( x - 1 )² or ( x + 1)²
